. STEFANUS NIELSEN, OF BROOKLYN, NEW YORK.

TYPE-WRITER.

Application filed May 10, 1916, Serial No. 96,501.

To all whom it may concern:

Be it known that I, S'rEFANUs NrsLsEN, a citizen of the United States,residing in the city of N ew'York borough of Brooklyn, county of Kings,an State of New York, have invented a certain new and usefulType-Writer, of which the following is a specification.

This invention is a typewriter, and the object of the invention is, moreparticularly, to improve typewriters of the class to which my co-pendinapplication Serial Number 17771, filed fiarch 29, 1915, relates.

lFrom a more specific standpoint, the obtanically driven meanscontrollable by the erator, and are returned to normal posi- ..on, outof engagement with the platen, by further mechanical means independentof the operator. There has been an objection to machines of thischaracter because of the fact that, if an operator were actuating themachine at high speed the type bars might not be returned quickly enoughfor a subsequent operation, and nomeans was provided for allowing of thesubsequent operation-of any particular type bar until it had been resetto its initial, inoperative position. The present invention providesmeans which entirely overcomes this disadvantage and allows the machineto be operated as rapidly as the most skilledoperator can actuate thesame.

Features of the invention, other than, those specified, will be apparentfrom the'. hereinafter detailed description taken in conjunction withthe accompanying drawin s.

n the accompanying drawings, I have illustrated different practicalembodiments of the invention, but the constructions therein shown areto, be understood as illustrative,

only, and not as defining the limits of the.

invention.

Figure '1 is a vertical section through a typewriter embodyin thepresent invention, sald section being ta on on the broken line XX ofFig. 2.

Fig. 2 is a'rear view of the machine, with certain parts broken away, oromitted, in

the interest of clearness.

Fig. 3 is a perspective detail showing a part of a type bar action, thetype bar belng shown in normal or rest position.

Fig. 4 is a view similar to that of Fig. 3, but illustrating a slightlymodified form of type bar action.

Figs. 5 and 6 are details showing difl'erent portions of the cycle ofoperation of the preferred form of type bar action.

Flg. 7 is a detail of one of the type bars of the machine, and-thecrating the same, and

Fig. 8 is a detail perspective of one of the elements of the modifiedconstruction.

Referring to the drawings, the type bars are designated by the referencenumeral 1.

:Ihese bars are pivoted at 2 in slots 3 formed in a supporting segment4. The type bars are mounted radially of the segment and are adapted,when actuated, to strlke the platen 1 at a common. printing point 5,being mechanically driven to said printing point by means of tensionsprings 6 in the manner clearly set forth in my co-pending applicationhereinbefore referred to.

Type bars 1 are held in their normal or rest positions against thetension of springs 6 by stop members 7- which are pivoted at mechanismfor op- 10 to brackets 11 mounted on a cross-beam 12, which, inturn, issupported by lugs 12 formed on the frame of the machine.-

13 designates the finger-keys which constitute the keyboard, and, in thepreferred embodiment of the invention shown in Figs. 1', 2, 3, 5 and 6of the drawings, each key 13 is provided with a stem, to the lower endof which 1's pivoted one arm-of a bell-crank 14 mountedfor 15. The otherarm of bell-crank 1 is pivpivotal movement on a pin oted to la push-rod1-6, the function of which pus rod is to actuate its cooperating stopmelt; er 7 in order to release tho-corresponding type bar '1 and allowthe associated. sprmgfi to move said bar to the print-.

' ach push rod 1J1 which is mounted between rollers 19 'ourcam 12, -Whenany particular key 13 is do;

as a guide piece18" 60 link will be disen is advanced one-fifth of acomplete rotation. Thus, bars 27 successively operate upon the links ofthe keys successively actuated. If more bars 27 were employed, thegearing would be such as to advanceone bar at a time to proper,operative position.

It will be manifest that some means should beprovided to govern thepivotal movement of links 9 so that the; will be presented to bars 27 1nsuch positions as to v be readily actuated thereby, and removed fromengagement with said bars as soon as the resetting operation of thatparticular type bar is completed. To this end, each type bar is providedat its rear end with a laterally projecting pin 26 which rests upon aguide tongue 26, and each sprin tongue 26 is of sufiicient length toexten beyond the termini 'of the travel of the pin 26. Guide tongues 26form a part of a plate 41 fixedly mounted on a. cross-beam 46, as shownin Fig. 1. Cooperating with tongues .26 is a like number of sprintongues 27 mounted attheir forward en s on bent-up portions 43 securedto a cross-bar 44. The forward ends of tongues 27 are in spaced relationto the corresponding ends of tongues 26*, while the rear ends of tongues27* rest lightly upon tongues 26* near their joining with plate l1, asshown in Fig. 3. Each pin 26 0t one of the links 9 cooperates with onepair of tongues withwhich said pin engages, and the inclinationorf'curvature of said tongues is such that the hookshaped portion 32 ofeach link is presented to the operating bars27 in proper position, and,after the llnk has been retracted to the desired extent, said tonguescause the link to be disengaged from the actuating bar 27 The manner ofoperation is clearly shown in Figs. 3,5 and 6. Fig. 5 shows thepositions of the parts when the type bar is at the printingpoint. Atthis time, link 9 is in its forward position and resting on the lowestportion of guide tongue 26. The letter having been printed at theprinting point, the platen advances, thereby allowin the spring motor torotate shafts 29, witthe result that one of th bars 27 engages with thehook-shaped portion 32 at the end of link 9, last operated. Bar 27advances, carrying with it link 9 and retracting 'said link to restposition, with spring 6: under tension. However, it will be noted from,Fig. 5 that, as the link is retracted, its pin .26 rides on. guidetongue 26, which slopes upwardly. The result of this construction issuch that, when the link has. been-re tracted sufliciently far, the book32 offthe ged from bar 27. Guide tongues 26* and 2 b are. soproportioned that this disengagement will occur as soonaspin "26haspassed under the free end of the co: operating spring tongue 27",simultaneously 6 with whichthe cooperating stop 7 will have 1113111181specified,

operation of the same ey, ',stop 7 would be 1 20 oscillated, notto,release projection 8, but

engaged with the projection 8 on the link and locked the link,inretracted position. The positions of the parts at this time are as shownin Fig. 2}, and they remain in such positions until the type bardsagain. released by its key? 13, at which time pin 26 will ride idly upand over its 'springtongue 27 until approximately that time at which thetype bar reaches the printing point,

whereupon it will have traversed the length of tongue 27 b and will fallinto engagement with its-tongue 26 or into the initial position shown inFig. 5. Each and every ype bar operates in the ing released by, itsfinger-key and actuated by its spring 6 to the printing point, afterwhich it is returned Y to its rest position by one of the bars 27, towhich its associate link is directed and subsequently removed by.,thecooperating 86 tongues 26" and 27*.

As heretofore stated, itmay happen that, when one letter is operatedtwice in succcssion, if the second operation too closely follows thefirst, not suflicient time has 90 elapsed to allow of the resettingmechanism returning the type bar to its rest position. before the secondoperation-takes place. -In this event, only one im rcssion would bemade, and this dilficulty as long been recognized in power-driventypewriting ma. chines.v According to the present inventipn, however,means is provided whereby the" waiting for the completion of.theresetting, 2) operation is rendered unnecessary, thereby 1010 greatlyincreasingths spqbd at which, the machine may 'be operated. This meansis embodied, in the preferred-form, in aheel 25 formed on each stop 7,and so positioned as to underlie the lower edge of link 9. The functionof heel 25'is"noth1ng more or less than to trip hook 32 of-link 9 freeand clear of bar 27 during. the resetting operation, since, by theprovision of means to accom: plish this result, the type bar is renderedat l all times within the control of the operator. Assuming, therefore,that link 9, shown in Fig. 5, has been engaged by onset the bars 27 andpartially retracted, it would be normally maintained in engagement withsaid bar until the retracting operation was com pleted. However, if thetypist is operating the machine, high peed and wishes to fol- W, thepreceding 0 eration b another to lift heel 25 into engagement with, and,thereafter raise, link 9, w1th the result Quit hook 32 of said link isdisengagcdirom bar 27 as shown in Fig. 6. Spring-6 will havc'umi beenplaced under -.sufiic1ent tension, and type bar 1 retracted tojsuch.extent, that, i even at'this' point, the second printing-operation willbe performg.mi certainty'and the proper impression'made.- i

The mechanism described, therefore, places all of the type bars underthe will of the operator'at all times, irrespective of the resettingoperation, and, accordingly, the

5 machine can not fail to carry out the operations of the most skilledoperator. To insure proper coiiperation between .heel 25 and link 9,i'rrespectiveoflthe particular portion or elevation of the spring tongue:26- with which it is in engagement, the lower edge'ol link'9 ispreferably curved or'shapedin such manner as to compensate for thedilference in elevation of different positions. The :lower edge of eachlink is so positioned that i5 during the operation of stop 7 inreleasing theprojection A, when the links are in normally retracted orrest'positions, the heel 250i the stop will not come into engagementwith the lower-edge of the link since at such times engagement of theheel with ,the link is not only unnecessary,.but would increase the workto actuate the stop. It is only during the resetting operation of anyparticular link that it is within the zone of operation of heel 25. I

Because of the fact that the type bars are pivoted on a segmentand thatthe resetting bars 27 are tangential to said segment there isnecessarily a slight difference of relation 80 between the pivotal pointon the various type bars and the difi'erent points along the length ofthe bars27- with which therespective links cooperate. In order to placethe links Sat all times during the resetting operation under thecontrolof the heel 25,

the. contour of the lower edge of each link.

is shaped so-that that portion ofthe lower edge of the link which is injuxtaposition with heel 25 during any particular period 40 of theresetting operation will be positioned relative to said heel that whenthe heel is operated, it will impart to the link just suiti- .c1entmovement to lift'it free from the resetting bar 27.

that shown in Figs. 1,3, 4, 5, and'G.

Moreover, because. of the fact that the typebars are pivoted formovement radially of the segment While the links 9 are mountedperpendicular to the tangential bars 27, it

will be manifest that only that link which cotiperates with the bars 27midway of the length thereof will lie in the same plane as itscoiiperating type bar. The links at either i side of this central linkwill lie in different planes of their respective type bars. horder toobtain proper pivotal action between the 7 type bars and the. links,those portions of the links whi'ch are pivoted to the type-bars shouldlie in the same plane,. fas the types -bars,"and, accordingly, suchlinks as are not in parallel relation with their ,coiiperating type:bars are twisted near their points of pivoting to bring the ivotedportion of the links into parallel re tion with said type Thus, the linkshown in, 45 Fig. 7 is of slightly difierent contour than bars. Thusthose portions of the links" which are pivoted to the type bars areparallel thereto and form proper pivotal connection.- T

In Fig. 4 is shown a slightly modified 1 form of means, controlled bythe lingerrkeys,

for releasing the type bars from their set positions. 111 accordancewith this modificzv tion, the key 13 is provided with a stem 48, to thelower end of which is pivoted a dog l9 normally maintained in alinementwith stem l8 by a spring 49. 51 is a rockshait carrying a fixed arm 50adapted to,

be engaged by dogACQJ The construction thus far described issubstantially the same as that illustrated in my co-pending applicationreferred to, the parts being so arranged that dog. 49 will leave arm 50after.

the key has been depressed tora certain extent, and thereby allow theshaft to return to its initial position after having been oscillated bythe depression of the finger key. Rock-shaft 5l'carrics at its rear enda stop 52 and a crank-arm 53, both of which are fined on the shaft. Stop52 is adapted to engage with a projection 5i, which is pivoted at 55 tolink 56, which link corresponds to link 9 of the preferred construction,The spring57 serves to hold projection 54: m a norn 1al,,extendedposition, because of its engagement ,with a movei'l'ient limit'ingmember 58 secured to said projection;

\Vhen rock-shaft 51 is operated by the depressing of key 13, stop 52 isoscillated out of engagement with projection 54, with the result thatspring 6 forces the type bar 1 to the printing point. lVhen the type baris subsequently returned through. the medium Iofthe resetting mechanismhereinbefore described, projection 54 will be retracted against thetension of its spring 57 and, in

this retracted position, will pass by stop 52. As soon as it has passedstop 52, spring 57 will throw the projection outwardly into engagementwith the back end of the stop, and the parts will be locked in restposition.

It will be noted that, whenever shaft 51 is rocked, arm 53 will be movedin accordance therewith, and this arm is so positioned that its end willoverhang one end 60 of a lever 61 whicliis pivoted, at 62, to a suitablesupport 63, The oscillation of rock-shaft5l will thus serve to pivotallymove lever 61, depressing end 60 and raising the opposite end..Said-opposite end is formed to underlie the lower edge of link 56, and,as a. re-

sult the pivotal movement of said lever, in the manner specified, servesthe same purpose as' the operations of heel 25 in the referredconstruction, viz., to release the from the resetting mechanism when thekey "is actuated before the resetting mechanism has completedtheresetting operation.- It thus appears that, in'the constructiondescmbed, the machine may 'beoperated at rut inv least intcrit clpositiveuess.

which the releasing ypo act Ill] lrlnn 'tliie resetting lllQCllitnism isaccomplis ed have been shown, and, in like minn'ier, variousmodifications might be illustrated With reference to the reset tingmechanism. However, I have shown only one, which illustrated in Fig. 8.In accordance with this modification, instead of having plates 28 Withbars 27 extending between them, which bars common to a plurality of typebar actions, each type bar action is released by a separate plate 58,havin projections 59 corresponding to bars 2'7, it being understood thatthe various plates 58 are successively positioned on drive-shaft 29,towhich movement is imparted. here-- inbefore described. Thus, instead ofhaving a plurality of bars 27 common to a plurality of type bar actions,each action has its own particular plate 58, having its resettingprojection 59.
